Why didn't Wu Xiubo's wife get a divorce?

Wu Xiubo and his wife don't divorce because they have the same interests. In the previous program, Wu Xiubo revealed that his wife is in charge of the family's financial power, including the house under her name. Chen Yulin revealed that she was a mistress in Wu Xiubo, and there were other women in Wu Xiubo, which did not cause much reaction from Wu Xiubo's wife. When he began to extort money, He Zhenya began to fight back because it touched her interests. Wu Xiubo and his wife have the same child, and they are constantly involved in economic affairs. So in the end, He Zhenya stood up and chose to fight back with her husband to safeguard her own interests, instead of choosing divorce.
